I also have problems with installing Trisquel 7.0 LTS Belenos DVD ISO (64bit)
on my PC
After GUI install, reboot I get only a shell with the following text:
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/4e2e4952-f2b0-4458-afe4-22f8cbe53ac1 does not exist.
Dropping to a Shell!
BusyBox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) built in shell (ash)
Enter 'help' for a list of built-in commands.
(initramfs)
looking on the internet, I'm not the only one that has this problem:
